What precautions are there for growing wood ear mushrooms?
The wood ear mushroom was originally a fungus that grew on rotten wood, and was later cultivated through continuous artificial trial growing to produce the artificially grown wood ear. It is relatively rich in nutritional value, and wood ear appears in the dietary therapy formulas for many ailments. Its main effects are nourishing the blood, invigorating blood circulation, nourishing the stomach and tonifying, among others. For modern health preservation it is a very good choice, so today let us first look at the precautions for growing wood ear mushrooms.
1. Time
In fact, we can now see wood ear mushrooms for sale in the market all year round, and the main reason is actually the progress of cultivation technology and the development of the food processing industry. Actually, the most suitable seasons for growing wood ear are summer and autumn each year, so when growing them, note that it is best to plant in May and June and in October and November each year.
2. Temperature
Wood ear mushrooms can only grow normally after the growing temperature reaches the standard. In fact, the temperature requirements of wood ear are mainly shown in that the temperature in the early stage of cultivation should be relatively low, then slowly raised, and after reaching a certain level slowly lowered again, which can speed up the growth of wood ear. But in ordinary management, the temperature of the growing room should basically reach the standard of 20 to 25 degrees.
3. Humidity
During the growth of wood ear mushrooms we need to manage humidity well. First, note that the wood ear logs used for growing should reach about 70 percent humidity; second, the humidity in the air should be at least about 80 to 90 percent; finally, throughout its growth process, we need to adjust humidity accordingly based on the mushroom emergence and the growth of the spawn, but no matter what, the growing humidity must absolutely not be lower than 6 percent.
4. Light
The wood ear mushroom is a relatively unique fungus and differs somewhat from other fungi, so when growing it we should note that from just after inoculation until the mycelium-running stage there must be no light. If there is light, then it is very hard to run the mycelium successfully. But when it emerges and when the mycelium grows, relatively strong light is needed for normal growth. So we should note the timing of its mycelium running and emergence, and then regulate the light accordingly, so as to ensure the yield and quality of the wood ear mushrooms.
5. Wood ear logs
For growing wood ear mushrooms, not all rotten wood can be used. So what we need to note is choosing the best wood ear logs and handling the logs scientifically. First, it is best to use Mongolian oak, white oak, elm, willow, mulberry, and the like; these trees are all relatively common, so the cost will not be too high. Second, the wood ear logs should preferably have a growth period of about nine years, then be sawn into small sections of about 1 m to 1.5 m, and be allowed to ferment as quickly as possible in a suitable environment. At the same time, we should check whether the log sections have borers or pathogens, and if so, clean and disinfect them promptly, which is beneficial to the growth of wood ear mushrooms.
6. Disinfection
In the process of growing wood ear mushrooms, a total of four disinfections are needed. First, after the nutrient medium is prepared, the nutrient medium needs to be disinfected. Second, disinfection is needed when handling the wood ear logs. Third, disinfection is needed when inoculating; this disinfection separately disinfects the inoculating personnel and the inoculating equipment, among others. Finally, disinfection is needed during emergence management and fruiting management, so as to avoid carrying bacteria in and affecting the normal growth of the wood ear mushrooms.
